Allow customer to look up record via one field entry.

Allow customer to look up record via one field entry.

I don't exactly know how to explain this so someone would understand - 

I have a parking citation application that I would like to be able to embed some type of search form, or report in a web page, and a driver can then go to the website, enter their license plate number (which is entered by the officer) and view their parking citation online. Is this possible? I know I can embed an entire report, but I can't figure out how to allow someone to search for their (and only their own) parking citation based on their license plate. 

Can someone help me with this?

Thanks!
